Thanks for all the contributions. Plenty to take in. It’s clear that the jury is still out as to whether cable discs would offer any significant overall benefit vs a well set-up calliper when paired with the 4600 levers. I read elsewhere that the Shimano option is the one to get for those levers bu...

How about using a thumb-shifter?

Thank you, very helpful.

re the "need" for MTB rear derailleur for large capacity, it depends what you mean by "large capacity" I guess, but we have on our tandem: Sora 9S RD running an 11-36 cassette Front chainrings 46/36/24 Both front and rear are two teeth beyond nominal capacity I think, but the wh...

Brucey wrote:FWIW Tiagra 4700 10s, GRX 10s and shimano 11s 'road' RDs all use the same shift ratio, so will all work from the same shifters.

So does that mean that those 10 speed RDs should work with 11 speed bar ends?

Thank you everyone for your helpful replies. All food for thought.

Dura Ace 9 speed bar ends and Shimano 9 speed MTB mechs have been my default combo for ages, and they work perfectly together. I don't know about Dura Ace 10 speed though. But as said, 9 speed MTB mechs are getting very thin on the ground anyway. TBH I would be perfectly happy to go with 9 speed ra...

However the 4700GS mech is running beyond its capacity and although not a problem I'm wondering if an mtb rear mech would be better suited, in which case what works with what? Shimano 9 speed rear MTB derailleurs are compatible with Shimano 10 speed road shifters (whereas 10 speed rear MTB deraille...

What are the options for a 3x10 speed set up using bar end shifters? On our tandem I currently have a Tiagra 4700GS rear mech with 4700 STI levers. I'm thinking of building up a new tandem and want to go down the route of bar end shifters. I'm assuming I could use the above rear mech with DuraAce 10...

Disagree completely. You can get enough oomph with a short allen key. In a kids bike I bet it will be poorly maintained enough to be a problem getting them out, not keeping them in. You're perfectly entitled to your opinion. :) Mine is based on many years of working in the profession. Personally I'...

One could try altering the current in the adv settings, though to do this you need to buy a programming cable and download the free software. Problem then with lowering current is the motor will likely run in efficiently. Even so doing this the motor won't be legal as it will be marked 750w. As I u...

OP Just hook that brake up as indicated. No disagreement there. Re the allen key and pedals thing. Many of us would actually say that such a tool would not only be fine but better than a spanner. You can't over tighten it that way and many pedals only have an allen key hole anyway. If it is as tigh...

Whilst I have no idea of what a Barracuda Phoenix looks like the answer to your question has to be no. When you say that the wheels seem to be the "main issue" what is the issue? I'm 6'1" and am perfectly happy riding a mountain bike with 26" wheels.

In any case, after finding the right allen key we managed to get it sorted. I hope you've managed to refit the front brake. I note that you managed to fit the handle bars and pedals "after finding the right allen key". Please note that you will not tighten the pedals sufficiently with an ...

Does the electricity supply to the garage come from the house? If so my first choice would be send the signal down that. The adaptors can also act as wireless base stations. This sort of thing although I'm not up to date on models: https://www.amazon.co.uk/TL-WPA4220KIT-Powerline-Broadband-Configur...
